Patent GB-2060325-A (GB)
Title: Squash ball warming device
IPC: A63B47/00
Filed: 1979-10-12
Abstract: A device for warming squash balls, to an optimum temperature prior to play, comprises a vertical hollow cylinder down which a ball can be dropped to rest on a spring-loaded shutter. A balance loaded electrical heating element adjacent the shutter heats the ball to the required temperature. When the ball is required for play, the shutter can be depressed to release the ball, which drops through into an open-fronted cage from which it can be removed. Two such cylinders are arranged side-by- side, beneath a hinged lid, so that two balls can be heated at the same time. <IMAGE>

Title: Improvements in or relating to presses
IPC: B22D17/14
Filed: 1980-02-20
Abstract: In a press of the type used for the compression, transfer and/or injection moulding of polymeric materials or of the type used for the pressure diecasting of metals, the incidence of defective mouldings or castings due to air or other gas being trapped in the mould or die during moulding or casting is greatly reduced by providing a shroud in two main parts (1 and 5), the lower main part (5) being metallic and being secured to a fixed press table (7) of the press. The upper main part (1) of the shroud comprises a rigid metallic member (1) fastened to an upper movable press table (3) and a flexible strip (1b, c, d, e) sealingly secured to the rigid metallic member (1). When the upper press table (3) is moved downwardly towards the lower fixed press table (7), around a mould (2, 6), the strip (1b, c, d, e) co- operates with an abutment sealing face (5a) on the substantially wholly rigid lower main part (5) of the shroud to produce a substantially closed chamber having an outlet (5b) for connection to a source of vacuum which will preferably maintain a vacuum of from 22 to 24 inches of mercury inclusive within said chamber. <IMAGE>
Patent GB-2045032-A (GB)
Title: Air-to-ground data transmission systems
IPC: F42B12/36
Filed: 1980-03-20
Abstract: The invention relates to air-to- ground data transmission systems for communication data from a low-flying object to a remote ground station (4) which is equipped with one or more receiving antenna. A substantial immunity from interference is achieved by feeding the data carried in the low- flying object (2) into a subsidiary store which is accommodated in a subsidiary flying body (5), e.g. a rocket, carried by the low-flying object (2). When the subsidiary store contains data for transmission, the subsidiary flying body (5) is ejected from the low-flying object in the direction of the ground station (4), until it reaches a reception zone from which the stored data can be securely transmitted by radio. The invention is particularly suitable for data transmission in connection with low-flying reconnaissance aircraft. <IMAGE>

The compressed air may be supplied by an engine driven piston pump via a solenoid or camshaft operated valve. <IMAGE>
Patent GB-2073918-A (GB)
Title: DC-DC converter
IPC: H02M3/335
Filed: 1980-04-10
Abstract: A DC-to-DC converter of the so- called flyback type has a switching transistor (1) which applies a pulsed waveform to the primary of a transformer (4). Thus during the pulses energy is stored in the core of the transformer (4), which energy is "dumped" via a rectifier (5) into the load when the pulse ends. The output voltage depends on the widths of the pulses applied to the transformer (4): to control this by an error signal is derived from the primary of the transformer and applied via a rectifier (7) to an amplifier (5), where it is compared with a reference voltage (VR). Any discrepancy between VR and the signal produces a control signal which is applied to a pulse width modulator (2), which suitably adjusts the widths of the pulses applied to the transistor (1). To avoid undesirable effects of overload a summing amplifier (8) and a pulse width limiter (3) ensure that when the load exceeds a preset level, pulse width is reduced. The summing amplifier (8) can have another input, shown by a broken line connection, so that changes in the input voltage can be taken into account. <IMAGE>

Title: Fluid flow regulator
IPC: F16K3/34
Filed: 1980-04-30
Abstract: An in-line fluid flow regulator has an opening (6) for the passage of fluid between its inlet and outlet, and a control member (12) supported coaxially with respect to the opening and surrounded by an elastically deformable ring (11) which tends to deform by varying amounts with changes of inlet pressure so as to vary the flow path or paths through the opening in a sense which tends to maintain the flow approximately at a set value, and means (15) for manually adjusting the position of the control member with respect to the opening to enable the set rate of flow to be varied. The flow regulator is particularly suitable for use with instantaneous electric water heaters, more especially for shower units. <IMAGE>

Title: Improvements in or relating to apparatus for creating a gaseous flow
IPC: F04F5/16
Filed: 1981-05-08
Abstract: Apparatus for creating a gaseous flow comprises four tubular flow- inducting units (1) disposed at the same axial location within a cylindrical housing (20), with their axes parallel to the axis 21 of the housing. Each unit (1) has an internal surface profiled to define a flow passage having a venturi therein. Supply ducting is provided in the unit for delivering compressed gas into the flow passage through a narrow annular orifice formed in the internal surface of the unit and located in the flow passage upstream of the constriction of the venturi. A compressed air manifold (22) surrounds the housing (20) and has respective connecting air lines (23) extending radially through the housing and connected to compressed air connections of the units (1). The supply of compressed air to manifold (22) is controlled by a valve (24). Upon supplying compressed air to the units (1), a primary airflow is induced axially through each unit and a secondary flow of ambient air in the housing is entrained around the flow- inducing units so that the resulting gaseous flow through the tubular housing is the sum of the primary and secondary air flows. <IMAGE>

Title: Sail powered vehicle
Inventor: HAMPTON MICHAEL WILLIAM
IPC: B62B15/00
Filed: 1982-03-04
Abstract: In windsurfing, steering is obtained by moving the mast about a universal joint to shift the centre of wind pressure. In applying a similar steering method to a vehicle mounted on wheels (or possibly skids), at least one wheel (or skid) 8 has to be pivotable to accommodate the wind-induced steering. In order to provide self-centering, without inducing uncontrolled oscillation or wobble, the wheel 8 is mounted about steering axis to incline forwardly at an angle X between 5 DEG  and 50 DEG  and its axis of rotation is offset forwardly by a distance Y, e.g. of up to 3 inches (7.5 cm), to reduce the distance by which the point of ground contact of the wheel 8 is behind the point of inter- section of the steering axis 10 with the ground. <IMAGE>
